Routing question / VXLAN #77

Closed jo-carter closed 1 year ago

jo-carter commented 1 year ago

Hello,

More a question than a feature request.

Does this work without ibgp peering / calico / pods having routable IPs from outside of the cluster ?

and if not, are there any plans to introduce a model similar to Big IP Controller where traffic is tunneled into the cluster from the external NGINX load balancer over VXLAN (or some other layer 2/3 tunnel) ?

Thanks.

Hi Jo, sorry I missed your comment for a few weeks.

Yes, peering or tunneling is NOT required, just native IP packets. All you need is IP connectivity between the Nginx LB Server, and the K8s node IPs ( same subnet, preferably ). If you look at the diagrams, you will see the Nginx Server on 10.1.1.4,5; and the K8s nodes on 10.1.1.8,10.

I have a completely separate Whitepaper using NginxPlus, Quagga BGP, Calico, and Nginx Ingress Controller. If this is what you want, check it out: https://www.nginx.com/resources/library/get-me-to-the-cluster/

We have several large customer with BGP backbones doing this on Premise.

So you have TWO options for getting traffic to your Clusters with Nginx. One with BGP, one without.
